Well, it appears that in addition to making his living by selling False information to gullible Christians, John Mackay is fully aware that he can only get away with his con in an environment where he can play emotions and limit the scope or duration of the material presented.
That is not surprising. Professional Biblical Creationists always try to minimize the risk of exposure and a slow, extended debate where emotion is limited (as a written debate over the internet must be), and where there is adequate time to research their assertions and present the facts that refute their position, is a place they know will be their downfall.
John Mackay is simply selling falsehoods for Jesus.
Look at his weasel word email.
Just tell them to put their money where their mouth is and put up someone to debate so we can see publicly who is making the blunders.
This is a public forum. The debate would be public and we would most definitely be able to see who is making the blunders.
As a fellow Christian, I am appalled by the Professional Biblical Creationists who make their living by preying on the gullibility of the Christian Laity.
